Sprinkler



March 10, 1936. c. c. ARMSTRONG SPRINKLER Filed Feb. 19, 1954 Patented Mar. 10, 1936 UNITED STATES PATENT OFFIQE s n- NKLEn Charles G. Armstrong, Peoria, 111., assignor to L. R. Nelson Mfg. Co. Inc", Peoria, Ill., a corporation of Illinois This invention has reference to lawnsprinklers of thatclass employing sprayheads extending laterally from and communicating with a water conductor. Specifically, the invention relates to spray-heads as well as to supporting members o'rfbases therefor.

One of the objects of the invention is to provide a supporting member or base of stamped metal for carrying a tubular hose member having a spray-head, said base adapted to be clamped upon l said'mer nber and having provision for protecting said spray-head from injury.

Another object is to furnish a stamped metal supporting base for a hose member in'which re- 15 sids great rigidity and sturdiness; that will serve to maintain the spray-head in proper position for service; and that can be readily attached While partially covering and wholly protecting the said spray-head from abuse.

20 The appended drawing illustrates the invention in its preferred form though it is to be understood that changes of minor nature may be made such as will be considered to lie within the spirit and intention of the invention and within the scope of the claims to follow.

In said drawing, Figure 1 is a plan of a device constructed according to the invention. Figure 2 is a longitudinal sectional elevation of the same, part thereof naturally being in transverse section. 30 Figure 3 illustrates in perspective part of a supporting base shown in the earlier figures. Figure 4 is a longitudinal sectional elevation of a part shown in Figures 1 and 2, part thereof being shown in transverse section. Figure 5 is a plan 35 of an apertured shell portion illustrated in Figures 2 and 4. Figure 6 is a vertical section of a part of the same taken on line B6 of Figure 5.

In Figures 1, 2, and 4 a tubular member I is provided whose ends are adapted for the recep- 40 tion of hose sections, for example, said member in this instance having a threaded extremity 2 to receive the swivel nut of the hose, neither of the latter being shown, while the other end carries a swivel nut 3 for a like purpose. At a posi- 45 tion between its ends the said member I has a laterally extended hollow knob portion 4 provided with a discharge orifice 5. Snugly seated within said portion 4 is a shell portion 6, Figure 5, whose wall 6' is provided with a series of discharge 50 openings I directed in such manner as to set up a whirling body of water for projection from said orifice 5 as a spray, the result, however, being old and well known in the art. Said member I is preferably fashioned from stamped metal and is 5 therefore relatively soft and ductile. Naturally,

therefore, if the extended knob portion 4 -,i s left exposed in use itwould be in danger of becoming distorted bychance blows, or perhaps. injured in.- tentionally by mischievouspersonsland, if; thus changed in form, having particular reference to, the wall having the mentioned orifice 5, the resulting spray issuing fromthe latter would be ineflective in producing. the best. results in the sprinkling act. In view of what might occurit is the purpose herein to provide a' protecting 10 shield. for the knob portion or spray-head, and this may preferably be furnished. as-part of the supporting base for the entire structurethus far described. Said base is preferably a stamping of metal of a stiffer and more blow-resisting type than the metal of the spray-head 4 and includes a substantially cylindrically curved central loopportion 8 to envelope a portion of the member-I, there being a raised extension 9,:thereof to; receive into it the said spray-head. orknobl, it. being observed that said extension; includes a' wall I8 forming a protectingshield forthetop of the knob, and having an opening. therein; somewhat larger in diameter than the orifice 5 in order that no part of said shield will lie in the path of the spray to issue from the latter.

The cylindrical portion 8 is extended laterally into portions I 2 and from each of these said portions extends an arm I3 preferably of channel form in order to provide rigidity. And it may be noted that bracing portions I4 are formed to connect the portion 8 with the arms I3 for stiffening purposes. A suitable member is provided for clamping the portion 8 upon the member I, which, in this particular instance, takes the form of a screw I5 which passes through holes I6 in the portions I2 and threaded into one of. them.

The cylindrical portion 8 is fairly rigid yet there is sumcient flexibility to permit the member I to be introduced between the portions I2 and to be seated in position as shown, whereupon the tightening of the screw or its equivalent holds the parts in rigid connected relation, the arms I3 lying in line with each other in a line paralleling the plane of the wall having the orifice 5.

I claim:

1. A sprinkling device of the nature described including in its construction a tubular conductor having an extended integral knob portion projecting laterally from its wall, there being an opening in a wall of said knob portion for the discharge of a water-stream laterally from said conductor, a base for supporting and stabilizing the conductor, the same having a loop portion to partially envelope said conductor, said loop portion having a bulbous extension to receive into it the said knob portion, part thereof overlying the wall of the latter having the named opening, and said extension having an opening at the opening of the knob portion.

2. A sprinkling device of the nature described including in its construction a tubular conductor having an extended integral knob portion pro- J'ected laterally from its wall, there being an opening in a wall of said knob portion for the discharge of a water-stream laterally from said conductor, a base for supporting and stabilizing the conductor, the same consisting of a single member having a loop portion at substantially the middle of its length to partially envelope said conductor, said loop portion having a bulbous extension to receive into it the said knob portion, part thereof overlying the wall of the latter having the named opening, and said extension having an opening larger than the said opening of the knob portion exposing the same.

3. The invention in accordance with claim 2 wherein is included means to secure the loop portion upon the conductor with the named openings in register.

4. In a sprinkling device, a water conductor having an integral hollow knob portion provided with an opening in its wall for discharge of water laterally from said conductor, and a supporting base consisting of a single member including a part to partially encircle and clamp about the conductor and enclose the said portion and having an opening for exposing the first said opening, said member extending in opposite directions from said part substantially in line with each in said wall for discharging water laterally from said conductor, a suporting base consisting of a single member including a looped portion to partially encircle the conductor and enclose the said portion and provided with an opening opposite and for exposing the first said opening, said member extending in opposite directions transversely from said portion, the resulting extensions being in alignment with each other, and means for clamping the portion about the conductor.

6. In a sprinkling device, a water conductor including a tubular knob portion provided with a substantially flat wall having an opening in its wall for discharging water laterally from said conductor, a supporting base consisting of a single member including a looper portion to partially encircle the conductor and of. bulbous form to surround the said portion, the same having an opening therein larger than the first said opening exposing the same and lying in close proximity thereto, parts of said portion at that side of the conductor opposite that having the first said opening being spaced from each other and each terminating in an extension, the extensions lying substantially in line with each other, and means for clamping the said looped portion about the conductor.

7. A sprinkling device including a water conductor including an integral hollow knob portion provided with a fiat wall having an opening in its wall for discharging water laterally from said conductor, a perforate shell portion seated in said knob portion, and a base of a single portion having a loop at substantially its middle length partially encircling the conductor, said loop having a part of a bulbous form provided with a wall opposite the first said opening and provided with an opening registering with the latter, the extremities of said loop lying in spaced relation to each other at that side of the conductor opposite that having said knob portion, and said extremities terminating in oppositely directed portions lying substantially in line with each other.

8. The invention in accordance with claim 7 together with means at the said extremities of the loop for clamping said loop upon the conductor.
